Abstract
The response of several leaf gas exchange parameters were monitored with decreasing leaf water potential in Phaseolus vulgaris L. leaflets. These included photosynthesis, transpiration, CO2 compensation point, ribulose 1,5-diphosphate carboxylase activity, boundary layer plus stomatal, and mesophyll resistance to diffusion of CO2. Mesophyll resistance was calculated under two assumptions: (a) the CO2 concentration at the chloroplast was zero, and (b) it was equal to the CO2 compensation point.Keywords
